Police searching for a missing Irish vet have cordoned off a burned-out car found close to her home in North Wales.
Catherine Gowing, 37, has been missing since she failed to arrive at work at the Evans Veterinary Practice in Mold, North Wales, on Monday.
North Wales Police said they are carrying out forensic examinations on a five-door Renault Clio which matched the description of Ms Gowing's vehicle and had been found torched.
A 46-year-old man from Gwynedd remains in police custody after being arrested on suspicion of her murder on Tuesday night.
Detective Superintendent John Hanson said "Following an appeal for information regarding the whereabouts of Catherine Gowing's Renault Clio motor vehicle, at about 7.15pm yesterday evening a member of the public contacted police regarding the discovery of a burnt-out car in Pinfold Lane, Alltami, near Mold.
"Attending police officers have been able to confirm this is a five-door Renault Clio but at this time we cannot be sure it is Catherine's car. The area has been cordoned off and forensically secured and an examination of the vehicle and immediate area continues to establish the vehicle's true identity and secure any evidence which may assist us to find Catherine."
The car was found around two miles from Ms Gowing's home in New Brighton, Flintshire.
The last recorded sighting of her was at a supermarket in Queensferry last Friday evening and officers have been scouring CCTV and carrying out a forensic examination of her home as they try to establish her whereabouts.
Appearing at a press conference on Thursday, Ms Gowing's sister Emma broke down in tears as she asked the public for help in tracking down her sister.
She said: "We are desperate to hear any news of Catherine's whereabouts. Please look, please search, please help us find our beautiful sister."
